Application filed February, 1910. Serial No. 546,310.

To all whom it may concem:

Be it known that I, SAMUEL E. TR1sLnn,. a citizen `rof the United States, residing at Dayton, inthe county of Montgomery Vand State of Ohio, `have invented certain 'new anduseful Improvements inlRadiato'rs, of which the following is a specification.

My invention relates to condensers or fluid cooling apparatus, and more particularly to radiators for cooling the vwater which has been circulated'about the cylinder of an' explosive engine, and'is 'especially adapted for .`use in automobile' radiators.

The object of the invention is to -greatlyI simplify the structure as well as the means and mode of operation of suchdevices, whereby they will-not only be cheapened in. construction, but will be rendered more effi.- cient and positive in operation, and unlikely to vet out of repair.

i further object is to' provide an improved form of conduit which will present. the maximum amount of surface to the atmosphe1e,andwhich will readily permit the expansion and conta'ction of the conduit, due to varying thermal conditions, without subjecting the, conduitto undue strain and thepossible rupture of the conduit.

Further objects are -to 'provide an improved form of radiator fin, which will present the maximum amount of cooling surface, an'd which will .interrupt and deflect the currents of air, breaking and dividing the currents lin'such manner as to secure the greatest efficiency; an additional object is to rovide a suitable brace for the conduits which at the same time will give to the structure a pleasing appearance, by forming a front of lcellular type, which at the present time is greatly desired, in automobile construction.

lAfurther object is to provide means for equal distribution yof the water supply to the entire series of conduits. y With the above primary andother incidental objects in view as will more fully appear in the specification, the'invention consists of the features of construction, the parts and combinations thereof and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims. y Referring to the drawings, Figure 1 is a front elevation, partly in section of the asfmm the radiator, showing the relation of the radiatmgfins and the reinforcing strip. Figs, 8 and 4 are detail views of the conduit View of the tin plate' after being scored but `before being formed. Fig.`6 is a detail per- 'spective view of two of the radiating tins after vthei forming operation, on an enlarged scale.A Fig. 7 is an elevation of the fin plate after the forming operation. Fig. S is a detail perspective view of the tins as applied to the tubular conduit forming a part of the present invention. Fig. .9 is a similar. view showing theradiator fins applied to a flat conduit similar to those inV common use. Fig. 10 is a perspective view of the fin construction wherein the tins are oppo'sitely 'disposed, for use between closely spaced conduits. Fig; 1l is-a perspectiye. view of several conduits with the interposed reinforcing strip whereby the cellular appearance of the front is produced.` Fig. 12' isaJ detail per- ,spective View of the reinforcing strip before being inserted between the conduits. Fig. 13 is a similar view of a modified form of the said strip. Fig. 14e is a. perspective view 'illustrating thecellular front produced by Fig. 13, between the conduits. Fig. '15 is a similar" view illustrating the application of the single strip shown in Fig. 13 to the flat conduits. Like parts are indicated by similar characters, of reference throughout the several views.

In construct-ing the radiator, thereis employed a frame or body having in the upper portion thereof an inlet chamber 1 and in wateror other circulating medium` is conducted from the engine or other apparatus to theinlet chamber 1 from which it is conductedto the chamber Q through a multiplicity vof parallel conduits 3. passage through the conduits the circulating medium gives off the heat previously acquired, and enters the outlet chamber 2 in a substantially cool condition from which it is returned to the engine onapnaratus to again complete the cycle.

Heretofore vmuch difficulty has been eX- perienced through lack of durability of the conduits and the tendency of the conduits to rupture through excessive expansion and sembled radiator.

Fig. 5 is a detail perspectiveinterposing two of the 'strips as shown 1nthelower portion an outlet chamber 2. rFhe During its Thecondits'forming a part of the'pres ent-invention are designed to afford the maximum radiating surface and are Ato some degree elastic to compensate .for expansion and contraction, and the seams are reduced `to one per conduit, thus reducing the danger..

' of leaks to lminimum.

A io

.The conduits 3 .each comprise aslieetof metal, corrugated or formed undulating,

which is folded upon itself to-br1ng'con- .divide the conduit into plurality of separate parallel passages 5 through -Whicli the circulating medium is conducted. In several figures of the drawings theinner corrugations have been shown W'ith dat or square faces which join or abut to separate the passages 5. However not all metal will permit the abrupt bending necessary to pro-k duce such fiat faces, and therefore in some instances thc corrugations Will be formed` with rounded sui-faces as in Fig. 4.

The corrugations in the sides of .the .con-

duit provide an excess of material to corn- .pensate for clianges'due to thermal variations, and even though through excessive expansion the abutting corrugations sepa-y rating the passages might be separated no.

harm wouldresult as it would onlyl permit a small quantity of the circulating-fluid to leak from one to anotlierof the passages 5,

Witlioutescaping from the conduit. ,The seams et of the conduits 3 are not pressed `to parallelism with thewalls of the conduit,

thereto, forming extended portions herein- To facilitate the .dispersion of the heat, it it customary to provide tins, points or pro- `jections upon the' conduits. An lmproved form of iin is herein provided, which is formed from a flat sheet of metal 7 by scoring or slotting the sheet inro'ws or series as at 8F ig. 5,b and afterward bending or forcing the strip of material between the -slots outward beyond the plane of the plate, thereby forming archesor loops Q 'attached 'at. opposite ends to the original portion of the plate. The loops 9 are preferably of angularv forma-nd alternatelyarranged as shown in F igs. 6,7', 8 and 9 whereby succes'- sve loops Will be out of registry with each other.

The iin plates are attachedto opposite `sides of the conduits?) with the main or original portion of the plate tangentialto the corrugations of the conduit walls,l leav ing openings intermediate the corrugations, and the fins lor loops projecting beyond the plate and forming a crisscross mass as shoivn Figs. l, 8 fand`9tlirougli which thejair: may freely circulate, and lwherein the aircurrent will be separated into`a mul-y titude of smaller currentswhich .will 'reach' every 'parti of the fin plate and the surface 'ofth e;con'duits., The section 10 of' the fin "plate between the'` rows of --slots 8, Wliich is the only portionI remaining in' thejorignal l' t plane of the plate is comparativelysmall and provides the surface for attachment to the Walls of the conduitsjj By 'this construcf`- ,I tion, both surfaces of substantially tlieen' ltire 'tin plate are utilized' as a [cooling surface, laddition .to the Walls vof` the con. duits intermediate the points of attachment oftheplate.

. .Under ordinary conditions each conduit 3 is proyidedwith tivo 'fn plates, one on each side.: )However in some Ainstances ,itfis desirable to closely space. the 1 conduits, Yin.

tvliich case, there may not be sufficient space intermediate the conduitsto receive tWoiin plates. To meet such `conditions the strips 8 of the `fin plate may be alternately pressed in' opposite directions asV shownin Fig. 10 -in `which* but oney fin plate would be used- 'between the conduits, thei plate being attached at the apeXof the loops to the ,adjacent conduit Walls.

It is desirable lto give toautomobil/era- -diators a pleasing appearance by providing a c ellulai` front, and alsoto brace the -conduits against undue vibration. This has been attempted by interposingI a reinforcf -ing strip between' the conduits and rigidly securing such strip to the wallsjof the conduit. vHowever such construction resisted the expansion andlcontraction' of the conduit and frequently results in rupture ofthe conduit Walls.v To ob/viatethis difficulty' is one of the objects of extending the'seams 4 beyond the, conduit Walls, as before mentioned.

'A reinfoi'cing,sti'ip 11 isforni'edby a plu-. rality ofreverse bends in the strip, parts of the structure beingtreduced to paral-4 lelism, thereby forming` a perpendicular with a plurality of lateral arms as shown in F ig, 12, Whichis interposed .between the seams and rigidly secured to the extended seams 4 and independent of the conduitv Walls, whereby it will notinterfere With the expansion and contraction of saidfwalls.V

Thev reinforcing strip as described and shown in Fig". l2 is' formed from a singlecontinuous strip of material; it is obvious however-'that the reinforcement might be made up of a plurality of pieces variously arranged. In Fig. '14 aic shown tWo strips 1Q having a plurality of angular bends therein interposedbetween the. seams of 'succeeding conduits, forming a' multiplicity 'of angularly arranged cells, While Fig. `1l5,

shows a single strip 1Q between the extended seams producing a series of triangular cells.

Figs. 9 and 15 show the tin plates and the `reinforcing strips applied to conduits of ordinary construction, except that they have the extended seams 4 before mentioned.

l @It has beenfound by experience that in the radiators of usual construction, the cen` trallyl located conduits carryl the greater portion of the water or other circulating medium, and that frequently the outermost conduits areesubstantially unused. It is therefore desirable, to provide for equal distribution of the water, which ,is attained by means of the distributing conduit 14 having 'therein a plurality of discharge orifices so Huid through the adjacent oritices^16, which would over burden the centralV conduits 3. To compensate' for the greater pressure and greatersupply at the point of connection of the "intake conduit, the discharge oriices 16 are more sparsely vlocated adjacent to the point of connection ofthe intake'conduit, and become more numerous as the distance Vfrom said point increases. The same result, it is obvious, might be attained by varying the size oftheoritices. The combined capacity of the discharge orifices is proportioned' linaccordance with the capacity of L @the intake, making `due allowance for' the 'changing of the direction of flow,7 friction, -etc.,.so that approximately all the openings are utilized and iuidsupplied equally/to all the conduitsf, whichresults in more even and thorough cooling of themass offtluid and greatly 'increases the"capacity.of the radiator. In order that: the fluid supply may be drawn equally from all parts ofthe outlet. chamber'Q, the discharge conduit 17 is similarly provided with intake orifices' sparsely located adjacent to the oiftake, con

- duit 18 and more numerous as the distance fromthe Aoftake connection increases; thus V the -su'ction which 4will be less at the eXtreme end ofthe pipe is compensated tor'by the l inreasedcombined area of the intake ori.

. tices. The result of this construction is an even distribution of the water which is subdivided into smallquantities passing through alliof the numerous pa-ssages 5 of the conduits 3, which causes the temperature to be lowered very rapidly to a comparative low degree, increasing both the efficiency and capacity of the radiator. 1 The materi l employed for the conduits and iin plates may be sheet brass, copper, gilding or any othensuitable metal or material having heat conductiyaproperties,\

u ,'While the invention has Vherein been described. in its relation to automobiles, for which it is especially adapted, it is to be understood the invention is not limited to such use, but that the same general construction may be employed for sundry other pur poses, forinstance in connect-ion with sta- .tionary hydrocarbon engines, in connection with refrigerating. apparatus for cooling the refrigerating media, or as a heatingdevice byf circulating hot water or steam through the device. To these and other uses as will readily occur to any one skilled in the art, the' construction maybe readily adapted with but few or no modications; I do not automobile radiator.

V From the above description it will be apparent that there is thus produced a device of the, character described., possessing the particular features of advantage before enumerated as desirable, but which ob viously is susceptible of moditication in its form," proportion, detail construction and arrangementof parts, without rdeparting from the principle involved'or sacricingany of lits advantages.
